Did you ever find a three shoe flywheel for your Truggy? I just got one for my trophy Truggy. On HPI's website under the Trophy Truggy click on optional parts, there you will find the correct flywheel, clutch shoes, & springs. Flywheel part number 67525, shoes 101199, & springs 101201. The flywheel is countersunk on the backside unlike the savage flywheel that is flush.I have a trophy 4.6 and I will change the clutch from 2 shoes to 3 shoes. I saw on eBay several clutch sistems , witch one is the correct for my trugy??. Please I am still learning. Thanks a lot.
